December 2, 20241 yr I noticed a message this morning "appcache degraded" but then when I refreshed the page it says "healthy". But doesn't look right to me (no temperature): Appcache 3 active * healthy If I try to do a smart test on that disk it does nothing and the l get nothing (it just starts and immediately stops) and the attributes page says: -Smartctl open device /dev/sdg failed So to me it sounds faulty, yet this is really weird as it's saying healthy most of the time.
December 2, 20241 yr Author Assuming it is faulty, and I'm thinking it is, what is the best way to work out which drive it is?
December 3, 20241 yr Author So this is weird. After restarting the drive temp is showing and I can do the smart test.
December 3, 20241 yr Community Expert Device dropped offline, this is typically a power/connection issue, replace cables and retest.
December 10, 20241 yr Author Solution After restarting I've had no more issues with it basically disappearing. But I was still getting CRC errors on this drive only. I swapped the cables (one at a time) and was still experiencing issues on this one drive only. I then replaced the drive entirely. Same thing. Finally, found a thread talking about this issue with this exact drive (Kingston 1TB SSD) in which Kinston advised that the 199 isn't a CRC error with this drive and the reporting of it as such should be disabled. Which I've done. So I don't understand the initial failure, still very strange. But that drive has been replaced so maybe it was faulty?? Anyway thanks all for your help and thought best to report back and close off this thread.
